ALARM-CLOCK.

Specification of Letters Patent.

Patented. June 30, 1908.

Application filed February 17, 1908. Serial No. 416,334.

To all whom it may concern:

Be it known that I, MARY JOSEPHINE GAL- LAGHER, a subject of the King of England, residing'at 107 Highbury, New Park, in the county of London, England, have invented certain new and useful Im rovements in Alarm-Clocks; and I do here y declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an alarm clock and is intended to provide a clock having combination of mechanism by means of which an audible alarm signal is given at any predetermined time combined with a means of illuminating the face of the clock from the interior and means for extinguishing the light at any predetermined time.

According to my invention I rovide a clock, the exterior of which may e of any suitable type mounted in a metal, wooden or other case, with an opal or semi-transparent glass dial with the usual hours marked thereon and also bypreference having suitably marked thereon small indications for facilitating the adjustment of certain regulating hands for setting the alarm and extinguishing apparatus hereinafter mentioned.

The interior of the clock is so constructed as to allow of the insertion of an oil lamp, candle, electric light or other source of illumination, the light being so placed that when it is burning the whole or any portion of the glass dial is suitably illuminated from the interior of the clock.

The clock movement provided with the usual springs, wheels, pinions of an alarm clock is referably mounted at the back portion of t e clock and behind the illuminating chamber, and may or may not have a reflector.

I prefer to make the shafts or the like carrying the hour and minute hands pass through from the back of the clock and across the illuminating chamber to the front of the dial.

In one form of my invention I attach to the tube on which the hour hand is fixed or to an convenient ortion of the said tube in the uminating cliamber an arm or lever which is made suitably adjustable, such adjustment being preferably effected by means of friction. This lever has for its object the retention in the upward position of a flap for a certain eriod of time regulated by the working 0 the clock and during this time the lamp etc. is allowed to remain alight. As soon as the movement has carried the hour hand for a certain distance and the lever or its equivalent has passed a given point it will allow the flap which may form or be fur nished with an extinguisher to fall down on the lamp and so put out the light.

Within a certain range the lever or its equivalent can be regulated so as to allow the extinguisher to fall at any required time, the object being to extinguish the light when it is not re uired, for instance, it may be set so that the ight will be extinguished at sunrise, while the alarm bell or the like is actuated at any time for which it is set by means of the usual hand devised for that purpose, the time at which such alarm is set having no relation to the extinguishing device for the lamp. And in order that my said invention may be better understood I will proceed to describe the same with reference to the drawing accom anying this specification, which showsa met 0d of applying my inven tion to a clock illuminated by means of an oil lamp.

Figure 1 is a front elevation of the clock; Fig. 2 is a side view with the door at one side of the clock open showing the mechanism for extinguishing the lamp; Figs. 3 to 5 show enlarged views of the lamp and extinguisher mechanism; Fig. 6 shows a modification hereinafter referred to.

The same letters of reference are employed to denote the same parts in all the views The dial a, of the clock is of the ordinary type usedwith alarm clocks but has an additional indicating scale I) thereon with indications extending over a period of hours. The clock and alarm mechanism are of the ordinary type.

Mounted outside the ordinary sleeve 0 carrying the hour hand and in frictional contact therewith is an additional sleeve d carrying at one end a pointer 3 which works over the scale I) and having mounted at or near the other end a projecting arm e carrying a pin f.

Referring now to the lamp this consists of an ordinary container 9 provided with projecting pieces h which slide into suitable guides k a sto being placed at m to insure that the container when slid into the clock stops in the ri ht position for the extinguisher mechanism to be actuated. n is a wick holder of ordinary type and p a handle for regulating the height of the wick, q is a plate which is mounted so as to turn on the wick tube. This plate is prolonged into or has formed with it a handle 1" capable of working between two stops .9 and 2. Attached to the plate are two brackets t and u, the bracket '6 carries at the top a spring extinguisher flap v, while the bracket 14 carries a bent lever 20. The bracket a has a pin 2 which limits the movement of the bent lever w in one direction.

It will be seen that the lever w is so shaped that one end thereof comes in front of the spring flap 1) in one position. WVhen the lamp is pushed. into position with the lever w set so as to hold the spring flap in the upward position the other arm of the said lever is in such a position that the pin on the arm a in the course of the rotation of the sleeve d comes against the said arm and. pushes against it until the spring flap o is released. The mechanism is shown in this position at Fi 2.

Tn order to insert the lamp so that the up per arm of the lever w may not interfere with the pin f the handle 7" operating the plate 9 is pushed over toward the stop 2 which puts the upper end of the said lever in such a position that as the lamp is pushed in it clears the pin f. After the lamp is in position the handle r is drawn back against the stop 3 which puts the lever w into such a position that it can be actuated by the pin f in the course of its rotation.

T o understand the setting of the clock it should be explained that the stationary scale I; attached to the dial, as shown in Fig. 1, has the hour three about opposite the forty minute division on the dial. Therefore, if the pointer 3 is set at the division three 011 the scale 6, and the hour and minute hands set at 12 oclock, the latter must move to the three oclock division, or before it will be time to extinguish the light, and the arm 6, must point to about the division. VIII on the dial before it can trip the lever w, Therefore, said arm must be placed on the sleeve d at an angular distance of 90 behind the pointer in setting the clock it is simply necessary to put the hour and minute hands back to 12 and then to draw round the pointer 3 until it comes opposite the time on the scale I) at which it is required to extinguish the light. This will, of course, carry the arm 0 around to a position 90 ahead of the pointer 3, and when later the hands of the clock move to the hour designated by the pointer 3, they will have carried the arm 0 and pinf o posite the VIII hour division on the dia The lamp is now set with. the extinguisher flap 1) behind the lever 10 with the arm 7" in contact with the stop 2 so as to prevent the pin f touching the mechanism while the clock is being set to the time. After this has been done the arm 0 is pulled over and the extinguisher mechanism is in position to be actuated. the next time when the clock comes round to the required time.

Fig. 6 shows a modified form of the invention. In this case in place of the scale 0, the hour hand is prolonged and carries a quadrant-shaped movable scale 4. The pointer 53 in this case has the end turned over to indicate its position with respect to the scale. This arrangement obviates the necessity of setting back the hands to 12 before setting the pointer 3.

Of course I do not limit myself to the exact details of construction shown, since the same may be Widely varied without departing from the spirit of my invention.

In order to keep the mechanism cool the chamber containing the light may be lined with asbestos or with any suitable non-conductor of heat, or a sheet of such non-conductor may be interposed between the light and the working parts and means may be provided for ventilating the chamber containing the lamp or other light.
